Typical Performance Curves
Applications Information
The ISL59920, ISL59921, ISL59922, and ISL59923 are
triple analog delay lines that provide skew compensation
between three high-speed signals. These devices
compensate for time skew introduced by a typical CAT-5,
CAT-6 or CAT-7 cable with differing electrical lengths (due to
different twist ratios) on each pair. Via their SPI interface,
these devices can be programmed to independently
compensate for the three different cable delays while
maintaining 80MHz bandwidth at their maximum setting.
There are four different variations of the ISL5992x (ISL5992x
will be used when talking about characteristics that are
common to all four devices).
